Multi-membered N-heterocyclesR 0690 Synthesis and Antifungal Activity of Novel 3,6-Diaryl-5H-[1,2,4]triazo-

lo[4,3-b][1,2,4]triazepines. — A mild and efficient, microwave-accelerated procedure for the synthesis of the triazepines (III) (10 examples) is developed. Some of the prod-ucts are screened for their antifungal activities. Derivatives (IIIa), (IIId), (IIIf) and (IIIg) show excellent activity against Aspergillus niger and Penicillium species, and good to moderate activity against Aspergillus flavus and Rhizopus species. — (GUPTA, M.; J.
